Question 515313
A car covers the first 39 km of its journey in 45 minutes and covers the remaining 25 km in 35 minutes.
 What is the average speed of the Car?
:
Total distance of the trip: 39+25 = 64
Total time of the trip: 45 + 35 = 80 min
Change 80 min to hrs {{{80/60}}} = 1/60 = 1.333 hrs
:
Average speed = dist/time
{{{64/1.333}}} = 48 mph
